hey guys this is my first write up for this forum, i dont know if anyone has done this before.. or have already made a thread about this....so i hope this help people. well i was bored today before the 4th of july BBQ and I felt like doing something to my car... i figured i should modify the stock intake system to get more air flow and dissipate heat... Las Vegas is a hot place... so with that said, keep all negative comments to yourself please.

i wanted to utilize the duct on the fog light covers i had. i figured using an old intake pipe, i could recreate the csl snorkle.

first off i cut the pipe to make fit in the duct,

secondly i cut a hole in the bottom corner of the stock air box.

and then i put the pipe thru the hole.

then re-assembled everything.. it was a total of 15 minutes of work. and 20 mins just to find the damn intake pipe in my garage lol

here are some pictures.

don't mind the fact i don't have a grill installed in the bumper.. stupid dealer gave me an mtech II grill rather than an m3, so i am waiting for the other grill to come in.




dont worry... i did put an intake filter in the box, i just didnt take the pic of it just so you can see it without the filter.

there was a better acceleration, and i hope this will better my gas mileage.

in the future i will loose the stock filter and integrate a knn cone filter inside of it, i already have the plans written out.
